UNSAFE ARMS AND AMMUNITION COMBINATIONS
Ammunition used in a firearm must be the same caliber or gauge as that marked on the firearm by
its manufacturer. If the firearm is not marked as to the caliber or gauge, or if it appears that the
original marking has been overprinted or changed, it is the responsibility of the gun user to have a
qualified person determine what cartridge or shell can be safely used in the firearm.
The firing of a cartridge or shell other than that for which the firearm is chambered can result in the
cartridge or shell rupturing and releasing high pressure gas that can damage or destroy the firearm
and kill or seriously injure the shooter and persons nearby.
There are countless combinations of specific cartridges and firearms which are unsafe. Many of
these unsafe combinations are recognizable because of specific differences between the similar
chamber and cartridge dimensions. It is not possible to list every unsafe combination; therefore, in
the interest of safety, use only the cartridge (or shell) designated by the firearm or ammunition
manufacturer for use in a specific firearm. The cartridge caliber or shotshell gauge must be marked
on the firearm frame, receiver or barrel by its manufacturer.
The practice of rechambering firearms is not guided by industry standards. It is possible that a
firearm which has been rechambered may not be rechambered properly or the rechambered caliber
may not be marked on the firearm. The firearm user is responsible to find out from a qualified
person the cartridge caliber or shell gauge for which the firearm has been rechambered.
